Water Treatment Chemicals Market to Reach $48.0 Billion by 2030
Market projected to grow from USD 40.2 billion in 2025 to USD 48.0 billion by 2030, supported by industrialisation, water scarcity and stricter wastewater regulations
The global water treatment chemicals market is projected to grow from USD 40.2 billion in 2025 to USD 48.0 billion by 2030, registering a CAGR of 4.5% during the forecast period. Growth is being supported by industrialisation, declining freshwater availability and increasingly stringent wastewater discharge regulations, alongside developments in sustainable treatment technologies.
Market Growth Driven by Water Treatment and Sustainability Needs
The report, “Water Treatment Chemicals Market by Type (Flocculants & Coagulants, Corrosion Inhibitors, Scale Inhibitors, Biocides & Disinfectants, Chelating Agents), Source, End User (Residential, Commercial & Industrial), And Region - Global Forecast to 2030,” projects continued expansion in the global market through 2030.
Product development is increasingly focused on environmentally safe and high-performance treatment solutions. These include bio-based coagulants, biodegradable scale inhibitors and smart chemical dosing systems designed to optimise chemical usage and reduce waste.
Digital monitoring technologies and modular plant designs are also contributing to treatment systems for industrial water reuse, desalination and zero-liquid discharge applications.
